PATTERN MECHANISM FOR LOOMS.

T 0 all whom it may concern Be it known that I, HENRY Banosnnr, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented cer tain new and useful improvements in Pattern Mechanism for Looms, of which the following is a specification.

My invention relates to pattern mechanism for looms, of the class which has a pattern surface, preferably'a pattern chain, for operating, through intermediate connections the drop boxes, and a supplemental pattern surface, ordinarily termed an auxiliary or multiplier pattern chain, for repeating certain bars of the box pattern chain.

The object of my invention is to improve upon the construction of the pattern mechanism of the class referred to, as ordinarily made, and more particularly to provide an improved reversing mechanism for a box pattern chain cylinder, through the multiplier pattern chain carried, on the multiplier pattern chain cylinder, which cylinders are in this instance both driven by worms, and worm gears.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have only shown in the drawings sufficient parts of a shuttle box pattern mechanism, and multiplier pattern mechanism, and operating mechanisms therefor, with my improvements combined therewith, sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :--Figure 1 is a front view of a box pattern, and multiplier pattern mechanism, with my improvements combined therewith. Fig. 2 is a plan view of some of the parts shown in Fig. 1, looking in the direction of arrow a, same figure. Fig. 3 is a section, on line 3, 3, Fig. 1, looking in the direction of arrow Z), same figure, and, Fig. 4 is a section, on line 4, 4, Fig. 1, looking in the direction of arrow 6, same figure.

In the accompanying drawings, 1 is a portion of a loom side or end frame, to which is secured a stand 2 which has meant ed thereon the frame 3 which forms a support for the several parts of the pattern mechanism. Secured to the lower'end of the stand 2 is a stand 4, which has a bearing 4' for the inclined upright shaft 5, see Figs.

1 and 2. The lower end of said shaft 5 has a bevel gear 6 thereon, which is driven by a bevel gear on the crank shaft of the loom, not shown. The upper end of the shaft 5, which is journaled in the bearing 1 see Fig. 3, on the frame 3, has secured thereon the bevel pinion 7, which meshes with and drives a bevel gear 8. The bevel gear 8 has its hub 8 loosely mounted on the horizontally extending worm shaft 9, see Fig. 2. The worm shaft 9 is journaled in suitable bearings on the frame 3. The hub 8 of the bevel gear 8 has a recess 8, see Fig. 2, in which extends the end 10 of a clutch lever 10, which has its hub pivotally mounted on a pin 11, see Fig. 3, on cars 12 on a collar 12, whichis secured on the worm shaft 9 by a set screw 13. The other end of the lever 10, which is preferably of yoke shape, extends downwardly, and is adapted to engage with its ends 10 the collar 14, which in this instance slides loosely upon the shaft 9. A helically coiled expansion spring 10* extends between the lever 10 and the collar 12, see Fig. 3, and acts to hold the end 10 in the recess 8".

The collar 14 has an annular groove 14, into which extends projections on the yoke shaped arm 15 onone end of a lever 15, see Fig. 3. The lever 15 has its hub 15 pivotally mounted on a stud 16 on the frame 3. The other end of the lever 15 is in this instance connected by'a wire 17 with the take-up mechanism of the loom, not shown, to operate said lever 15 in case of picking out, and slide the collar 14 to the right in Fig. 3, which, through its engagement with the end 10 of the lever 10, raises the end 10 of said lever out of the recess ,8" of the hub 8 ofthe gear 8 to disconnect said gear.

The inner end of the worm shaft 9 has secured thereon a gear 18, see Fig. 2, which meshes with and drives a gear 19 on a second worm shaft 20, which is journaled in suitable bearings onthe frame 3. The worm shaft 20 has secured on its other end a worm 21, see Fig. 3, and the shaft 9 has fast thereon the worm 22, see Fig. 1. The worms 21 and 22 in this instance revolve in opposite directions, as indicated by the arrows in 1. The worm 22 is in mesh with and drives the worm gear .23, which has its hub 9/: loosely mounted on an elongated sleeve 24, see Fig. 1, which in this instance is secured to the pattern chain shaft 25. A key 24 on the sleeve 24, acts to communicate the rotation of the worm gear 23 to the sleeve 24 on the pattern chain shaft 25. The pattern chain shaft is journaled in suitable bearings 3", see Fig. 1, on the frame 3, and has a rotary box pattern chain cylinder 26 secured thereon, which is adapted to carry a flexible pattern chain of ordinary construction, not shown, in the usual and well known way.

Fast on the pattern chain shaft 25 is a dis; 54, which has a series of recesses in its periphery, and combined with the disk is a weighted roll 55, see Figs. 2 and 3, which is mounted in the yoked shaped end of an arm 56, which has its hub 56 pivotally mounted on a shaft 57, suitably mounted. The roll 55, in connection with the grooved disk 5%, acts to hold the shaft 25 from rotary motion when the worm gear 23 is out of mesh with the worm 22.

Extending over the box pattern chain cylinder 26 are in this instance two box indicator levers 27, and 23, see Fig. 2, to be operated by the pattern chain in the usual and well. known way. A. hand wheel 29 is this; on. one end of the pattern chain shaft 25, see Fig. 1. Also extending over the pattern. chain cylinder 26, and the pattern chain, not shown, thereon, is the pattern indicator lever 30, see Figs. 1 and 2. The end of said lever 30 is connected by the downwardly extending wire or rod 31 to the end of a lever 32, which has its hub 32 pirotally mounted on a stud on the frame 3, see Fig. 3. The lever 32 is adapted to be raised and lowered according to the indications of the pattern chain on the box pattern chain cylinder 26, which operates the indicator lever 30. Tl'irough the raising of the lever 32 the multiplier pattern chain shaft 34:, see Fig. 1, is raised. The shaft 34 rests with one end in this instance upon the lever 32, see Fig. 1, and has its end suitably guided in an elongated slot in the bracket 3. The other end of the nuiltiplier pattern chain shaft 34 is suitably journaled in the sleeve collar 35, which is pivotally mounted and held within a slot in the bracket 3 by two pointed set screws 36, see Fig. 4E. The hand wheel 37 is fast on the outer end of the multiplier pattern chain shaft 34. A worm gear 33, which is fast on the shaft 3 1, is, by the raising of the multiplier pattern chain shaft 34, carried into mesh with the worm 22, see Fig. 1, which causes the multiplier pattern chain shaft 34; to revolve, and also the multiplier pattern chain cylinder 39 fast thereon.

On the multiplier pattern chain shaft 34 is fast a disk 53, which has a series of recesses in its periphery. Combined with the disk 53 is a weighted roll 59, see Figs. 2 and 3, which is mounted in the yoked shaped end of an arm 60, which has its hub 60 pivotally mounted on the stud 11. The roll 59, in connection with the grooved disk 58, acts to hold the shaft 34 from rotary motion when the worm gear 33 is out of mesh with the worm 22.

The multiplier pattern chain cylinder 39 is adapted to carry a multiplier pattern chain, not shown, in the usual way.

Extending over the multiplier pattern chain, and the cylinder 39, is in this instance a lever 40, which has its hub 10 pivotally mounted on a stud 41, see Figs. 1, 2, and a. The end of the lever 40 is adapted to engage with a set screw 42 in the end of the arm 43, which arm has its hub 13 pivotally mounted on a stud 44 on the frame 3. Extending downwardly from the hub 43' of the arm 13 is a second arm 43", see Fig. 1, which has a stud 15 on its end, to which is pivotally connected one end of a connector 46. The other end of said comiector 4:6 is pivotally connected to a stud 47 on an upright lever 4-8, which has its hub -18 pivotally mounted on a stud 49, on the bracket or arm 3 on the stand 3, see Fig. 3. A helically coiled torsion spring 50 encircles the hub 48 of the lever 43, and acts to move baclm'ardly the lever -18, to the position shown in Fig. 1. The upper end of the lever 48 is provided with a screw 51, which is adapted to extend into an annular groove in the hub 23 of in!) the worm gear 23. The raising of the indicator lever 10 causes, through intermediate connections, the upright lever 48 to operate and move toward the left in Fig. 1, and also causes the worm gear 23 to move toward the left in l ig. 1, and into mesh with the worm 21, see Fig. 1, which, through its revolution in the opposite direction from the worm 22, causes the box pattern chain cylinder 26 to reverse as long as the lever 13 remains in this position, and until the multiplier pattern chain indicates the lowering of the indicator lever 40. A. washer or disk 52 is in this instance yieldingly held against the sleeve 24, see Figs. 1, and 2, by the expansion spring 53, and acts to yieldingly limit the outward movement of the worm gear 23.

The operation of my improvements in pattern mechanism for looms is briefly as follows :---ll"ith the parts in the positidn shown in 1, with the lever 40 in its lowered )OSltlOll, and the worm gear 23 in mesh with the worm 22, and the box pattern chain cylinder 26 revolving in a forward direction, the lever 30 is in its raised position, through a roll on the box pattern chain, not shown, extending under said lever, and the worm gear 33 is in mesh with the worm 22, which will cause the multiplier pattern chain cylinder 39 to revolve until a roll on the multiplier pattern chain, not shown, comes under and raises the lever 10. The raising of the lore 10, through the intermediate connections 13, 16, and -18, will more the sliding worm gear out of mesh with the worm 22, and into mesh with the worm 21, to cause the Cil reverse movement of the box pattern chain cylinder 26. If the box pattern chain cylinder 26 is revolved in a reverse direction a number of picks, there will be no roll on said box pattern chain under the lever 30. This will allow the lever 30 to be lowered, and through the intermediate connections 31 and 32, the worm gear 38 will be lowered out of mesh with the worm 22, and the multiplier pattern chain cylinder 39 will remain at rest until a roll on the box pattern chain, not shown, on the box pattern chain cylinder 26, comes under the lever 30, to raise said lever, and to raise the worm gear 38, and the multiplier pattern chain will be started to indicate the position of the gear 93, with reference to the worms 21 and 22, as explained above.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In pattern mechanism for looms, a box pattern chain cylinder to carry a pattern chain, a. worm gear slidably mounted and connected therewith, two worms, and means for revolving said worms, and automatic means to slide said first mentioned worm gear into engagement with one of said worms, and out of engagement with the other of said worms, to cause the revolution of said box pattern chain cylinder in a forward or backward direction.

2. In pattern mechanism for looms, a box pattern chain cylinder to carry a pattern chain, a worm gear slidably mounted and connected therewith, two worms to revolve in opposite directions, and means for revolving said worms, and automatic means to slide said first mentioned worm gear into engagement with one of said worms, and out of engagement with the other of said worms, to cause the revolution of said box pattern chain cylinder in a forward or backward direction.

3. In pattern mechanism for looms, a box pattern chain cylinder to carry a pattern chain, a worm gear slidably mounted, and connected therewith, two worms, and means for revolving said worms, a second pattern chain cylinder to carry a. pattern chain, and automatic means controlled thereby to slide said first mentioned worm gear into engagement with one of said worms, and out of engagement with the other of said worms, to cause the revolution of said box pattern chain cylinder in a forward or backward direction.
